General Information - Yamaha XT660R S Service Manual

GENERAL INFORMATION

This motorcycle is equipped with an immobilizer system to help prevent theft by registering codes in
standard keys. This system consists of the following:
• a code re-registering key (with a red bow)
• two standard keys (with a black bow) that can be re-registered with new codes
• a transponder (which is installed in each key bow)
• an immobilizer unit
• an ECU
• an immobilizer system indicator light
The key with the red bow is used to register codes in each standard key. Do not use the key with the
red bow for driving. It should only be used for registering new codes in the standard keys. The
immobilizer system cannot be operated with a new key until a code is registered in the key. If you
lose the code re-registering key, the ECU, main switch, and immobilizer unit must be replaced.
Therefore, always use a standard key for driving.
NOTE:
Each standard key is registered during production, therefore, registering the keys at purchase is not
necessary.
CAUTION:
• DO NOT LOSE THE CODE RE-REGISTERING KEY! If the code re-registering key is lost, reg-
istering new codes in the standard keys is impossible. The standard keys can still be used
to start the motorcycle, however, if code re-registering is required (i.e., if a new standard
key is made or all keys are lost) the entire immobilizer system must be replaced. Therefore,
it is highly recommended to use either standard key and keep the code re-registering key
in a safe place.
• Do not submerse the keys in water.
• Do not expose the keys to excessively high temperatures.
• Do not place the keys close to magnets (this includes, but not limited to, products such as
speakers, etc.).
• Do not place heavy items on the keys.
• Do not grind the keys or alter their shape.
• Do not disassemble the key bows.
• Do not put two keys of any immobilizer system on the same key ring.
• Keep the standard keys as well as other immobilizer system keys away from the code re-
registering key.
• Keep other immobilizer system keys away from the main switch as they may cause signal
interference.
